Occasionally (about twice a week) Premiere freezes on me. When importing assets or exporting media Premiere freezes and it happens at the point where Windows tries to display the window. Part of it will be drawn, and then it freezes. It has happened for both 2017, 2018 and 2019 versions, and I have little hope it has disappeared in the new 2020 version. The "file dialog" is part of Windows, so the problem is not necessarily an Adobe Premiere problem. However, no other app that I use has the same problem. In Premiere I use "Auto Save" heavily but it is still well annoying when it happens. Haven't been able to find a pattern.
